A method and wireless device for conduction transactions at a point-of-sale terminal using the wireless device is disclosed and may include initiating a transaction with the point-of-sale terminal via a wireless link, receiving at least one price from the point-of-sale terminal, determining whether the at least one price satisfies a price warning condition, and transmitting a signal if the at least one price satisfies the price warning condition.

RELATED APPLICATIONS

This application is a Continuation of and claims priority to U.S. patent application Ser. No. 12/434,463 filed on May 1, 2009 entitled “PROXIMITY PURCHASE RINGTONES,” which is assigned to the assignee hereof and hereby incorporated by reference in its entirety.

DESCRIPTION OF THE RELATED ART

As wireless devices evolve, they are being used more increasingly to conduct transactions with point-of-sale (POS) terminals. Near field communication (NFC) may allow a wireless device, e.g., a cellular telephone, to be used to make a close proximity purchase using the same frequency as contactless credit cards or contactless debit cards. The wireless device may automatically decide which payment instrument, i.e., which user account, to present to a point-of-sale terminal at the time of purchase. Since this process may be automated, a user may not easily know which payment instrument is selected for the transaction.

Accordingly, what is needed is an improved system and method of conducting transactions using a wireless device.

DETAILED DESCRIPTION

The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any aspect described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects.

In this description, the term “application” may also include files having executable content, such as: object code, scripts, byte code, markup language files, and patches. In addition, an “application” referred to herein, may also include files that are not executable in nature, such as documents that may need to be opened or other data files that need to be accessed.

In this description, the terms “communication device,” “wireless device,” “wireless telephone,” “wireless communications device,” and “wireless handset” are used interchangeably. With the advent of third generation (3G) wireless technology, more bandwidth availability has enabled more electronic devices with wireless capabilities. Therefore, a wireless device could be a cellular telephone, a pager, a PDA, a smartphone, a navigation device, or a computer with a wireless connection.

Referring to FIG. 1, a transaction system is shown and is designated 100. As shown, the transaction system 100 may include a wireless device 102 and a point-of-sale (POS) terminal 104. When the wireless device 102 is close to the POS terminal 104, the wireless device 102 may be connected to the POS terminal via a wireless connection 106. In a particular aspect, the wireless connection 106 may be provided by near field communication (NFC).

As shown in FIG. 1, the wireless device 102 may include a processor 110. A memory 112 may be connected to the processor 110. Further, an NFC reader 114 may be connected to the processor 110. In a particular aspect, the processor 110, the memory 112, the NFC reader 114, or a combination thereof may serve as a means for executing one or more of the method steps described herein. As shown, the wireless device 102 may be connected to, communicate with, or include, a database 116. The database 116 may include information about various items for sale. For example, the database 116 may include price information about various goods based on location, sale, etc. The database 116 may be queried using an item name, an item stock keeping unit (SKU) number, an item universal product code (UPC), an item location, some other identifier, or a combination thereof.

The POS terminal 104 may also include a processor 120. An NFC reader 122 may be coupled to the processor 120. Moreover, the NFC reader 122 within the POS terminal 104 may include an RFID chip 124. The RFID chip 124 may be a FeliCa card, a FeliCa tag, a Mifare card, a Mifare tag, or a combination thereof. Alternatively, the RFID chip 124 may be an ISO 14443-compliant contactless card. In another aspect, the RFID chip 124 may be an ISO 18092-compliant contactless card. Otherwise, the RFID chip 124 may be another contactless card well known in the art.

In a particular aspect, the RFID chip 124 may include information related to a merchant, e.g., a merchant identification. The merchant identification may include a merchant identification number, a merchant name, a merchant store number, or a combination thereof. In a particular aspect, the processor 120, the NFC reader 122, the RFID chip 124 or a combination thereof may serve as a means for executing one or more of the method steps described herein.

As illustrated, the POS terminal 104 may be connected to a merchant server 130. The merchant server 130 may include a processor 132 and a memory 134 that may be connected to the processor 132. In a particular aspect, the processor 132, the memory 134, or a combination thereof may serve as a means for executing one or more of the method steps described herein. The merchant server 130 may also be connected to a database 136. The database 136 may include customer information, e.g., loyalty card information. Further, the database 136 may include coupon information.

The various aspects described herein make use of wireless proximity-limited communication technologies to exchange files, e.g., loyalty card information, coupon information, merchant information, other information, or a combination thereof, between devices. A variety of wireless proximity-limited communication technologies may be used for this purpose. Examples of proximity-limited communication technologies include: near-field communications (NFC) protocol technologies; Bluetooth® protocol technologies; wireless personal area networks (WPAN) technologies based upon IEEE 802.14.4, including ZigBee®, WirelessHART and MiWi specifications; and infrared communication technologies, such as the IrDA (Infrared Data Association) protocol.

NFC technology devices operate in the unregulated RF band of 13.56 MHz and fully comply with existing contactless smart-card technologies, standards, and protocols such as FeliCa and Mifare. NFC-enabled devices are interoperable with contactless smart-cards and smart-card readers conforming to these protocols. The effective range of NFC protocol communications is approximately 0-20 cm (up to 8 in.), and data communications terminate either by a command from an application using the link or when the communicating devices move out of range.

However, the aspects and the claims are not necessarily limited to any one or all of the NFC protocols, and instead may encompass any close range (i.e., proximity-limited) wireless communication link. The Bluetooth® communication protocol is another suitable close range communication link that may be used. Bluetooth® transceivers may be configured to establish communication links automatically or in response to user commands as part of the various aspects as are provided for in the Bluetooth® protocol. The IrDA (Infrared Data Association) protocol may be used since the infrared transceivers must be within visual range of each other in order to establish a communication link, thereby restricting communications to situations where two mobile device users are cooperating to establishing the communication link. Short range wireless communication technologies, such as WPAN technologies based upon the IEEE 802.15.4 protocol may also be used, perhaps with range limiting features such as reduced transmission power level. In addition, other close range communication protocols and standards may be developed which may be used in the various aspects in the same manner as NFC, Bluetooth®, IrDA, and WPAN protocol devices.

Further, longer range wireless technologies and protocols may be used with modifications or additions that limit their effective range for purposes of identifying electronic devices one to another. For example, IEEE 802.11 (WiFi) (which communicates using the 2.4 GHz frequency band) and UWB (Ultra Wideband) wireless communication protocols and standards may also be used in combination with range-limiting features. For example, the power of transmitters may be limited for authentication communications, such that two devices must be relatively close together (e.g., within a few feet of each other) in order to send and receive the communications contemplated in the various aspects. As another example, round-trip communication delay limits may be imposed such that authentication communications may only occur if the round trip of such signals is less than a threshold set to reject signals sent from more than a dozen feet or so, and maybe as short as two to three feet separation.

For simplicity of reference, the various aspects and the claims refer to “close range communications” and “near field communications” in order to encompass any and all wireless proximity-limited communication technologies. References herein to “close range communication links” and “near field communications” are not intended to limit the scope of the description or the claims in any way other than the communications technology will not exchange credential information beyond the immediate vicinity of a user, which may be about three meters (about twelve feet). In a preferred aspect, the close communication range is limited to less than about one meter (about three feet), in a further preferred aspect, the communication range is limited to less than about one foot, and in some aspects the communication range is limited to approximately 0-20 cm (up to 8 in.). In order to reflect this distinction, descriptions of aspects using links with communication ranges of approximately 0-20 cm (up to 8 in.) refer to “NFC protocol” links. Therefore, references to “NFC protocol” communications are intended to be limited to communications transceivers and technologies with ranges provided by the various NFC protocols and standards listed above, but may also include technologies with a similar limited communication range.

With close range communications like NFC protocol devices it is easy to connect any two devices to each other with a secure wireless data link to exchange information or access content and services. Solution vendors argue that the intuitive operation of NFC protocol systems makes the technology particularly easy for consumers to use (“just touch and go”), while the inherent security resulting from its very short communication range makes such systems ideal for mobile payment and financial transaction applications. Familiar applications of NFC protocol technology are electronic pass keys used in building security systems, mass transit fare card systems, and smart credit cards which need only to be brought close to a point of sale reader to complete a transaction.

Referring to FIG. 2, an exemplary, non-limiting aspect of a wireless device is shown and is generally designated 220. As shown, the wireless device 220 includes an on-chip system 222 that includes a digital signal processor 224 and an analog signal processor 226 that are coupled together. As illustrated in FIG. 2, a display controller 228 and a touchscreen controller 230 are coupled to the digital signal processor 224. In turn, a touchscreen display 232 external to the on-chip system 222 is coupled to the display controller 228 and the touchscreen controller 230.

FIG. 2 further indicates that a video encoder 234, e.g., a phase alternating line (PAL) encoder, a sequential couleur a memoire (SECAM) encoder, or a national television system(s) committee (NTSC) encoder, is coupled to the digital signal processor 224. Further, a video amplifier 236 is coupled to the video encoder 234 and the touchscreen display 232. Also, a video port 238 is coupled to the video amplifier 236.

Further, in a particular aspect, the power supply is a rechargeable DC battery or a DC power supply that is derived from an alternating current (AC) to DC transformer that is connected to an AC power source.

In a particular aspect, the wireless device 220 may further include a global positioning system (GPS) module 282 that may be couple coupled to the DSP 224, the analog signal processor 226, or a combination thereof. The GPS module 282 and at least one of the processors 224, 226 may provide a means for locating the wireless device 220 either alone or in conjunction with network information available to the wireless device 220, e.g., using a table available to the GPS module 282 via a wireless network.

FIG. 2 further shows that the wireless device 220 may also include a network card 284 that may be used to access a data network, e.g., a local area network, a personal area network, or any other network. The network card 284 may be a Bluetooth network card, a WiFi network card, a personal area network (PAN) card, a personal area network ultra-low-power technology (PeANUT) network card, or any other network card well known in the art. Further, the network card 284 may be incorporated into a chip, i.e., the network card 284 may be a full solution in a chip, and may not be a separate network card 284. The wireless device 220 may further include a payment module 286. The payment module 286 may execute one or more of the methods steps described herein.

Further, the processors, 224, 226, the payment module 286, the memory 244, the instructions stored therein, or a combination thereof may serve as a means for performing one or more of the method steps described herein.

Referring now to FIG. 3 through FIG. 8, a method of conducing transactions at a wireless device is shown and is generally designated 300. The method 300 commences at block 302 with a do loop in which when a wireless device placed near a point-of-sale (POS) terminal, the following steps are performed. At block 304, a payment module within the wireless device may initiate a transaction with the POS terminal via a wireless link, e.g., an NFC link or other link described herein. At block 306, the payment module may determine a payment selection, e.g., based on one or more user preferences, a hierarchy of payment methods determined by a user, or a combination thereof.

Moving to decision 308, the payment module may determine whether an audible signal is associated with the payment selection. If so, the method 300 may continue to block 310 and the payment module may transmit an audible signal to the user via the wireless device, e.g., one or more speakers therein.

The audible signal may be a song, a song clip, a ringtone, a voice tone, a spoken message, or a combination thereof. The audible signal may be user defined, preset on the device, or a combination thereof. Further, the audible signal may indicate type of payment, e.g., a debit account, a credit account, a gift account, a rewards account, etc. The audible signal may also indicate a name associated with a debit account, a credit account, a gift account, a rewards account, etc. Moreover, the audible signal may indicate a merchant to which payment is being made. The audible signal may also be used to indicate that a price satisfies a warning condition, e.g., that a price is too high when compared to similar items in a database.

The audible signal may be used to indicate that a coupon is valid or invalid. Also, the audible signal may be used to indicate that a coupon is accepted or not accepted. Further, the audible signal may be used to indicate that a total amount due satisfies a warning condition, e.g., that a total amount due is too high based on one or more user defined settings. The audible signal may indicate that a debit account does not contain sufficient funds to pay for an item or combination of items. The audible signal may indicate that a debit account balance satisfies a warning condition, e.g., that the debit account balance is below a predetermined, or user determined, amount.

The audible signal may indicate that a credit account does not include sufficient available credit to pay for an item or combination of items. Further, the audible signal may indicate that a credit account balance satisfies a warning condition, e.g., that a credit account balance is higher than a predetermined, or user determined, amount. The audible signal may indicate whether a payment is approved by a merchant point-of-sale terminal The audible signal may indicate whether a final total satisfies a final total warning condition, e.g., that a final total warning condition exceeds a predetermined, or user determined, amount.

The method 300 may then proceed to block 312 and continue as described herein. Returning to decision 308, if the payment selection does not include an audible signal associated therewith, the method 300 may move directly to block 312.

At block 312, the payment module may receive an item description. The item description may include a SKU number, a UPC code, an item size, some other item identifier, or a combination thereof. In the case of multiple items, the payment module may receive multiple item descriptions. At block 314, the payment module may receive an item price, or prices.

Moving to block 316, the payment module may determine the location of the wireless device, e.g., by accessing a GPS module within the wireless device. At block 318, the payment module may search a database using each item description, location, SKU number, a UPC code, an item size, or a combination thereof in order to determine one or more comparative prices of each item. Thereafter, at decision 320, the payment module may determine whether any price equals, or satisfies, a warning condition. The warning condition may be based on a comparison between the price received from the POS terminal and a price determined after a search of the database. The warning condition may occur if the price from the POS terminal is higher than the price within the database. Further, the warning condition may occur if the price from the POS terminal is a pre-defined percentage higher than the price within the database. For example, the percentage may be five percent (5%), ten percent (10%), fifteen percent (15%), etc.

If each price does not equal the warning condition, the method 300 may continue to block 322 and the payment module may transmit and acknowledgement to the POS terminal to continue the transaction. Thereafter, the method 300 may continue to decision 342 of FIG. 5. Returning to decision step 320, if any price equals, or satisfies, a warning condition, the method 300 may continue to block 324 of FIG. 4 and continue as described herein.

At block 324 of FIG. 4, the payment module may transmit an audible signal to a user via the wireless device, e.g., one or more speakers therein. The audible signal may be a user defined song clip, a user defined ringtone, a spoken message, i.e., a voice tone, that indicates a price of an item is too high, or a combination thereof.

Moving to decision 326, the payment module may determine whether the transaction involves multiple items. If so, the method 300 may continue to block 328 and the payment module may query the user to remove an offending, i.e., over-priced, items and proceed. At decision 330, the payment module may determine whether to proceed based on the query at block 328. If so, the method 300 may move to block 332 and the payment module may transmit a request to the POS terminal to remove the over-priced items. Thereafter, at block 334, the payment module may receive an acknowledgement from the POS terminal The method 300 may then proceed to decision 342 of FIG. 5 and continue as described herein.

Returning to decision 330, if the payment module determines to not proceed with the transaction, the method 300 may move to block 336 and the payment module may end the transaction. The method 300 may then end.

Returning to decision 326, if the transaction does not involve multiple items, the method 300 may move to block 338 and the payment module may query the user to determine whether the user wishes to continue with the transaction and purchase the over-priced item. At decision 340, based on the query in block 338, the payment module may determine whether to proceed with the transaction. If so, the method 300 may continue to decision 342 of FIG. 3 and continue as described herein. Conversely, if the payment module determines not to proceed with the transaction, the method 300 may move to block 336 wherein the transaction may be ended by the payment module. Thereafter, the method 300 may end.

Moving to decision 342, the payment module may determine whether a coupon is selected. If a coupon is selected, the method 300 may move to decision 344 and the payment module may determine whether the coupon is valid. If not, the method 300 may proceed to block 362 of FIG. 6 and continue as described herein. Otherwise, if the coupon is valid, the method 300 may move to block 346 and the payment module may transmit the coupon the POS terminal At block 348, the payment module may receive an acknowledgement from the POS terminal At decision 350, the payment module may determine whether the coupon is accepted, e.g., based on the acknowledgement from the POS terminal If the coupon is not accepted, the method 300 may move to block 352 and the payment module may transmit an audible signal to the user via the wireless device, e.g., one or more speakers therein. The audible signal may be a user defined song clip, a user defined ringtone, a spoken message that indicates the coupon is not accepted, or a combination thereof. Thereafter, the method 300 may continue to block 364 of FIG. 6 and proceed as described herein.

Returning to decision 350, if the coupon is accepted, the method 300 may proceed to block 354 and the payment module may transmit a request for a total amount due from the POS terminal Block 354 may also be reached from decision 342 if a coupon is not selected. Moving to decision 356, the payment module may determine whether the total amount due equals, or satisfies, a warning condition. The warning condition may be a threshold amount over which the user wants to be warned, e.g., fifty dollars ($50), one hundred dollars ($100), two hundred fifty dollars ($250), five hundred dollars ($500), etc.

If the total amount equals, or satisfies, the warning condition, the method 300 may continue to bock 358 and the payment module may transmit an audible signal via the wireless device, e.g., one or more speakers therein. The audible signal may be a user defined song clip, a user defined ringtone, a spoken message that indicates the total amount due exceeds a warning threshold, or a combination thereof. Thereafter, at decision 360, the payment module may determine whether the user would like to proceed with the transaction, e.g., by querying the user. If not, the method 300 may end. Otherwise, the method 300 may move to decision 370 of FIG. 7. The method 300 may also proceed to decision 370 of FIG. 7 when the total amount due does not equal the warning condition at decision 356.

Returning to decision 344, if the coupon is not valid, the method 300 may move directly to block 362 of FIG. 6 and continue as described herein. At block 362 of FIG. 6, the payment module may transmit an audible signal via the wireless device, e.g., one or more speakers therein. The audible signal may be a user defined song clip, a user defined ringtone, a spoken message that indicates a coupon is invalid, a spoken message that indicates a coupon is expired, or a combination thereof. At block 364, the payment module may query the user to continue the transaction without the coupon. Next, at decision 366, the payment module may determine whether to proceed with the transaction based on the query above. If so, the method 300 may return to block 354 and continue as described herein. Otherwise, the method 300 may proceed to block 368 and the payment module may end the transaction. The method 300 may then end at.

Returning to decision 356 of FIG. 5, if the total does not satisfy the warning condition, the method 300 may proceed to decision 370 of FIG. 7. Also, at decision 360 of FIG. 6, if the payment module determines to proceed with the transaction, the method 300 may also proceed to decision 370 of FIG. 7.

At decision 370, the payment module may determine whether the payment selection received at block 306 of FIG. 3 is a debit card or a credit card. If the payment selection is a credit card, the method 300 may proceed to decision 372 and the payment module may determine whether the proper amount of credit associated with the credit card, or credit account, is available. If not, the method 300 may proceed to block 374 and the payment module may transmit an audible signal to a user via the wireless device, e.g., one or more speakers therein. The audible signal may be a user defined song clip, a user defined ringtone, a spoken message that indicates the account associated with the selected credit card does not have enough available credit, or a combination thereof. Thereafter, the method 300 may proceed to decision 400 of FIG. 8 and continue as described herein. Returning to decision 372, if the account associated with the selected credit card has sufficient credit available, the method 300 may proceed to decision 376 and continue as described below.

Returning to decision 370, if the payment selection is a debit card, or debit account, the method 300 may proceed to decision 378 and the payment may determine whether the debit account has sufficient funds. If not, the method 300 may proceed to block 380 and the payment module may transmit an audible signal to a user via the wireless device, e.g., one or more speakers therein. The audible signal may be a user defined song clip, a user defined ringtone, a spoken message that indicates the debit account does not have sufficient funds for the transaction, or a combination thereof. Thereafter, the method 300 may proceed to decision 400 of FIG. 8 and continue as described.

Returning to decision 378, if the debit account contains sufficient funds, the method 300 may move to decision 376. The method 300 may also move to decision 376 from decision 372 when the credit account selected has sufficient credit available. At decision 376, the payment module may determine whether an account balance, e.g., credit account or debit account, equals, or satisfies, a warning condition. For example, if the account balance is above a threshold for a credit account or a below a threshold for a debit account, the account balance may equal the warning condition. If the account balance equals, or satisfies, the warning condition, the method 300 may proceed to block 382 and the payment module may transmit an audible signal to a user via the wireless device, e.g., one or more speakers therein. The audible signal may be a user defined song clip, a user defined ringtone, a spoken message that indicates a credit account balance is too high, a spoken message that indicates a debit account balance is too low, or a combination thereof. Then, the method 300 may proceed to decision 400 of FIG. 8 and continue as described.

Returning to decision 376, if the account balance does not equal the warning condition, the method 300 may proceed to block 384 and the payment module may transmit information to the POS terminal. At block 386, the payment module may receive an acknowledgement from the POS terminal At decision 388, the payment module may determine whether payment is approved. If payment is not approved, the method 300 may move to block 390 and the payment module may transmit an audible signal to a user via the wireless device, e.g., one or more speakers therein. The audible signal may be a user defined song clip, a user defined ringtone, a spoken message that indicates payment is not approved, or a combination thereof. The method 300 may then continue to decision 400 of FIG. 8 and continue as described.

At decision 388 if payment is approved, the method 300 may proceed to block 392 and the payment module may request a receipt, e.g., an electronic receipt (“e-receipt”), from the POS terminal. At block 394, the payment module may receive the receipt from the POS terminal Further, at decision 396, the payment module may determine whether the final total equals, or satisfies, a warning condition. The warning condition may be a threshold amount over which the user wants to be notified, e.g., fifty dollars ($50), one hundred dollars ($100), two hundred fifty dollars ($250), five hundred dollars ($500), etc.

If the final total equals, or satisfies, the warning condition, the method 300 may continue to bock 398 and the payment module may transmit an audible signal via the wireless device, e.g., one or more speakers therein. The audible signal may be a user defined song clip, a user defined ringtone, a spoken message that indicates the final total exceeds a warning threshold, or a combination thereof. At decision 396, if the final total does not equal the warning condition, the method 300 may end.

Proceeding to decision 400 of FIG. 8, the payment module may determine whether a new payment method is received from the user. If not, the method 300 may move to block 402 and the payment module may end the transaction. Thereafter, the method may end. If so, the method 300 may proceed to decision 404. At decision 404, the payment module may determine whether an audible signal is associated with the payment selection. If so, the method 300 may continue to block 406 and the payment module may transmit an audible signal to the user via the wireless device, e.g., one or more speakers therein. The audible signal may be a user defined song clip, a user defined ringtone, a spoken message that indicates the type of payment, a spoken message that indicates the source of the payment, or a combination thereof. The method 300 may then return to decision 370 of FIG. 7 and continue as described herein. Returning to decision 404, if the payment selection does not include an audible signal associated therewith, the method 300 may return to decision 370 of FIG. 7 and continue as described herein.

It is to be understood that the method steps described herein do not necessarily have to be performed in the order as described. Further, words such as “thereafter”, “then”, “next”, etc. are not intended to limit the order of the steps. These words are simply used to guide the reader through the description of the method steps.

Further, it may be appreciated that many of the notifications or warnings described herein occur when a negative event occurs, e.g., when a price satisfies a warning condition, when a coupon is not valid, when a coupon is not accepted, when credit is not available, when funds are not available, when a payment is not approved, etc. However, the user may be also notified when a positive event occurs, e.g., when a price does not satisfy a warning condition, when a coupon is valid, when a coupon is accepted, when credit is available, when funds are available, when a payment is approved, etc. In such instances, these notifications may also be ringtones, voice tones, song clips, or combinations thereof.

With the configuration described herein, the system and method disclosed herein provides a way to automatically warn, or notify, a user of certain events while conducting transactions using a wireless device. For example, when a certain credit card is used, a first ringtone, voice tone, song clip, or combination thereof may be transmitted or emitted to the user. When a different credit card is used, a second ringtone, voice tone, song clip, or combination thereof may be transmitted or emitted to the user. As such, these ringtones, voice tones, etc. may be used to inform the user which payment instrument is used for a purchase. These ringtones, voice tones, etc. may be pre-loaded on a wireless device, loaded later by a user, customized by a user, or a combination thereof.

In a particular aspect, if there are multiple payment instruments used for a particular purchase, e.g., the combination of a coupon and a credit card, multiple ringtones may be played when the payment instruments are accepted by the point-of-sale terminal Also, the wireless device may emit a ringtone, voice tone, song clip, or a combination thereof, when a POS terminal reads a selected payment instrument.

In another aspect, different ringtones, voice tones, etc. may be transmitted to the user for different error conditions, e.g., when a credit card is declined authorization, when a credit account reaches a maximum credit limit, when a debit account reaches a minimum amount, when a coupon is invalid or expired, when a coupon is rejected, when a stored value loyalty card is decremented to a zero value, when a gift card is decremented to a zero value, when a store loyalty card is rejected, etc.

Additionally, if the amount of the purchase is available to the wireless device, another ringtone, voice tone, etc. may be transmitted to the user. For example, when a transaction is over a predetermined amount, e.g., one hundred dollars ($100), a particular ringtone, voice tone, etc., may be transmitted to the user. If the transaction is less than the predetermined amount, another ringtone, voice tone, etc., may be transmitted to the user. The audible feedback provided for herein may allow the user to more easily know the amount of a transaction, i.e., how much money is charged to a credit account or deducted from a debit account minus a coupon amount.

In another aspect, the pitch of the ringtone, voice tone, etc. may be increased when a transaction exceeds a particular threshold. When the transaction is below the threshold, a lower pitch ringtone, voice tone, etc. may be transmitted to the user. Conversely, when the transaction is above the threshold, a higher pitch ringtone may be transmitted to the user.

In one or more exemplary aspects, the functions described may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software, the functions may be stored on or transmitted over as one or more instructions or code on a computer-readable medium. Computer-readable media includes both computer storage media and communication media including any medium that facilitates transfer of a computer program from one place to another. A storage media may be any available media that may be accessed by a computer. By way of example, and not limitation, such computer-readable media may comprise RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium that may be used to carry or store desired program code in the form of instructions or data structures and that may be accessed by a computer. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of medium. Disk and disc, as used herein, includes compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk and blu-ray disc where disks usually reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above should also be included within the scope of computer-readable media.
